The Spacecraft graveyard or cemetery in the South Pacific is a disposal site for spacecraft at the end of their lives. Mir space station rests there. The ISS plans to join it. Defunct satellites are also dumped in the ocean graveyard. Earth's Atmosphere: Layers of Dynamic Design Human Microchip Implants: Pros & Cons Solar Panels & Batteries in Space This vast expanse of ocean, far from any major landmass, is the designated impact zone for decommissioned spacecraft. Controlled deorbits guide spacecraft and satellites to their final resting place in the SPOUA. The logic is to minimize risk of uncontrolled re-entry and potential damage on populated areas. But as the space industry booms and more satellites enter orbit, concerns are raised about close and long-term implications. Known scientifically as “Point Nemo,” this site is 2,688 km from the nearest land. This hopes to ensure the re-entering debris is not a threat to humans. Water Pollution: Eight Countries in Crisis Extreme Heat: Effects on Infrastructure Air Pollution: Science, Health & Economy The most prominent potential resident of the SPOUA is the International Space Station (ISS). The orbiting lab is scheduled for demolition at the end of 2030. Several years of planning go into its deorbit and crashdown. When bringing a defunct satellite back to Earth, the primary goal is to avoid uncontrolled re-entry. Otherwise pieces of spacecraft survive descent through the atmosphere and potentially cause damage at ground level. The remote stretch of ocean is about the size of Argentina, is believed statistically to be the safest place on Earth to drop space debris. The process of controlled deorbit uses thrusters to slow the satellite. It descends into Earth's atmosphere. Friction with air generates intense heat, burning up much of the satellite. Some heavier components, made of heat-resistant materials like titanium, are likely to survive re-entry. Titanium (Ti): From Space to Earth & Back Space Debris: Coping with Dangerous Junk Building Robots: Elastomers, Metals & Plastics International Space Station Thus it's guided to fall into the graveyard. A major concern is marine pollution from hazardous materials used in spacecraft. For instance, hydrazine, a common rocket propellant, is highly toxic. It can leak into the ocean and decimate marine life. Even small amounts of hydrazine can disrupt reproductive systems of fish and other organisms. The cumulative effect of disposing of spacecraft in this area is not fully understood. Persistent pollution can and will threaten marine biodiversity. For example plastic pollutants accumulate toxins in fish. CubeSats: Science, Technology & Risky Business Space Satellites: Mechanics & Materials Earth Communication: Satellites, Spacecraft & Astronauts Russian space station Mir now rests in the spacecraft graveyard Further complicating matters are legalities surrounding the SPOUA. It's in international waters beyond the legal jurisdiction of any single country. The Outer Space Treaty, enacted by the UN in 1967, states space should benefit all nations and is free from territorial claims. A significant loophole arises, regarding disposal of spacecraft in the ocean. With the cemetery lying outside any country’s jurisdiction, determining liability for potential damages gets complicated. Similarly, the UN Convention on the Law of the Sea focuses primarily on marine pollution from ships and land-based sources. This also leaves a legal gap regarding deposition of spacecraft debris in the ocean. Lasercom: Laser Communication in Space Top 5 Countries of the Global Space Race Semiconductors: Materials, Methods & Markets Growing Problem of Space Debris Use of the SPOUA is just one facet of the larger problem of space debris . The majority of space debris is defunct satellites, discarded rocket stages and fragments from collisions and explosions. The orbital junk is a major threat to operational satellites and future of space exploration. As number of satellites in orbit grows, risk of collisions and creation of more debris increases exponentially (Kessler Syndrome). As the spacecraft cemetery builds up with obsolete satellites, the problem of space debris increases, with many more junkers to be dumped into the sea in the near future. The ocean already carries the giant Pacific garbage patch.

Earth's atmosphere is made of layers, each with certain characteristics and functions. From weather at ground level to the expanse of space above, the atmosphere is a dynamic and fascinating complex of natural forces. Lasercom: Laser Communication in Space Human Microchip Implants: Pros & Cons Satellite Radio Waves: Type & Function image: NASA Layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. They surround the Earth like gaseous shields. 1. Troposphere: Weather Closest to the Earth's surface, the troposphere is the layer in which humans live. Extending from ground level to approximately 7-20 km (4-12 mi), it contains most of the atmosphere's mass and almost its water vapor. The troposphere is about 78% nitrogen and 21% oxygen, with trace amounts of other gases like argon, methane and carbon dioxide. Every day one adult tree releases oxygen equal to breathing needs of two humans. Wildfires & Climate Change: Lethal Cycle Bioremediation: Organic Cleanup of Toxins Effects of Extreme Heat on the Human Body Temperature decreases with altitude, causing formation of clouds, rain and wind. Mountaintops are colder than valleys. Air pressure is highest at the ground level, decreasing with ascent. All weather phenomena, like clouds, rain, and storms, occur at this level. Turbulence is caused by significant vertical air movement, mixing and contributing to weather patterns. The troposphere's thickness varies with latitude. It's thicker at the equator, where heat from the sun causes the air to rise. At the poles it's thinner due to colder temperatures. Thickness can vary up to 20%. Magnetic Fields & Space Travel Genetic Engineering: Biotechnology of Change FSO: Wireless Transmission By Light Beam Arctic ice 2. Stratosphere: Ozone Layer Above the troposphere, the stratosphere, reaches up from 7-20 km to 50 km (4-31 mi). This layer is more stable than the troposphere. It contains the ozone layer, which absorbs 97-99% of the Sun's UV radiation. Temperature increases with altitude. This is due to the absorption of ultraviolet (UV) radiation by the ozone layer. Air pressure continues to decrease with altitude, at a slower rate than in the troposphere. With less vertical mixing, the stratosphere is fairly stable. Jets often fly in the lower stratosphere, at altitudes of 10-14 km (6-9 mi), to avoid turbulence. The ozone layer is concentrated in the middle stratosphere. Ozone depletion heightens concerns about increased UV radiation reaching Earth's surface. According to the Word Health Organization, cases of skin cancer are on the rise. Fossil Fuels: Ecology & Economy Carbon Dioxide (CO2): the Good & the Bad Silicon (Si) Metalloid: Prehistory into the Future 3. Mesosphere: Shield from Space Debris Extending from 50-85 km (31-53 mi), the mesosphere is the coldest layer of the atmosphere. Air pressure is very low. Temperatures drop 59 -90°C (-130°F). Meteors and satellites burn up in this layer due to friction with air. Noctilucent Clouds, the highest clouds in the atmosphere, sometimes appear in the mesosphere near the poles in summer. The mesosphere sits above the stratosphere, extending from about 50 to 85 kilometers (31 to 53 miles) above sea level. In this layer, One of the mesosphere's defining features is its role in the disintegration of meteoroids. Most meteoroids burn up here to create shooting stars. This phenomenon happen s about 75 km (46 mi) above ground. Despite its importance, the mesosphere is studied less than other layers due to its altitude and difficulties of exploration. Only a few specialized research missions have successfully gathered information. Humans in Space: Effects on Body & Mind Cryptocurrency Scams: Goodbye, Money Super Alloys in Space Exploration 4. Thermosphere: Aurora Borealis & Satellites The thermosphere extends from 85-600 km (53-372 mi). It is characterized by extremely high temperatures up to 2500°C (4500°F), due to the absorption of highly energetic solar radiation. Air pressure is extremely low. The ionosphere overlaps with the thermosphere and exosphere. This region is ionized by solar radiation, enabling radio communication. Aurora borealis and australis happen here. Charged particles from the sun collide with atoms and molecules in the thermosphere, creating amazing auroral displays. Many satellites also orbit in the thermosphere. While the thermosphere is huge it has few air molecules and a very low density. Thus, even at extremely high temperatures, an object wouldn't feel hot in this region. Space Debris: Coping with Dangerous Junk How Solar Panels Work Semiconductors: Materials, Methods & Markets International Space Station & aurora in the thermosphere 5. Exosphere: Edge of Space The outermost layer of the atmosphere, the exosphere, extends from 600 km (372 mi) outwards, eventually fading into the vacuum of space at 10,000 km (6200 mi).  In this layer, the atmosphere begins to resemble a vacuum. Temperature is variable, influenced by solar activity. Air pressure is extremely low and air is very thin. It's made primarily of hydrogen and helium atoms. They can travel hundreds of km without colliding. The exosphere gradually thins out, with atoms escaping into space. Some satellites and space debris orbit in the exosphere. It has no weather and is inhospitable to known life. Solar Energy & Nuclear Power in Space Slime Mold: Brainless Wonder & Evolutionary Link Scam Centers in Southeast Asia Forget you saw me. Beyond the Exosphere: Space Beyond the exosphere is space. It's no longer part of Earth's atmosphere but the realm of interplanetary and interstellar space. A vacuum, its density of matter is extremely low. It's subject to intense radiation from the sun and other cosmic sources. Space has no air pressure. Temperature varies from -270°C (-454°F) in the dark to over 120°C (248°F) in sunlight, but can reach absolute zero and is much hotter near stars. Earth's atmosphere interacts with the interstellar medium, showing past periods of increased interstellar material, including hydrogen and other elements. These affect the atmosphere and potentially climate. Interstellar media can cause increased hydrogen levels, global noctilucent clouds and a reduction in mesospheric ozone. This can even start ice ages.  Charged particles from the solar wind are found here, and interplanetary magnetic fields extending from the sun. Sound doesn't exist as sound waves can't travel without a medium like air. High levels of cosmic radiation are a problem for space exploration but also provide valuable data for scientists. The radiation consists of charged particles emitted by the sun. Electrons, protons, and helium nuclei, they're expelled during solar flares and coronal mass ejections. Solar wind, a stream of charged particles and magnetic fields from the sun, carries radiation through the solar system.  Cassava Root: Nutrition, Toxins & Economy Microchips: the Real World Power Regions of Extreme Heat: The Future is Now Sylvia Rose Books READ: Lora Ley Adventures  - Germanic Mythology Fiction Series READ: Reiker For Hire  - Victorian Detective Murder Mysteries Back to Top

Solar energy and nuclear power are the two major forms of energy in space. Solar panels are familiar on satellites and spacecraft. Nuclear energy fuels deep space missions. De-Orbiting Satellites: Problems & Processes Space Debris: Coping with Dangerous Junk Survival of Bacteria in the Extremes of Space image: NASA Solar Energy: Power of the Sun Solar panels installed on spacecraft capture sunlight and convert it to electrical energy. This method is most often used. On Earth, clouds and atmosphere reduce solar efficiency. In the vacuum of space solar panels gather energy unhindered. NASA's Solar Dynamics Observatory uses solar to generate energy for operating complex scientific instruments and communication systems. Solar power converts sunlight to electricity using photovoltaic (PV) cells. The principle is relatively simple. PV cells, usually made with the metalloid silicon, absorb photons from sunlight to convert them into electrical current. Solar Panels & Batteries in Space How Spacecraft Produce Water for Astronauts What Robots Need to Function & Survive solar powered CubeSats - European Space Agency (ESA) A typical solar panel can convert around 15-20% of solar energy into usable electricity, making it a reliable energy source close to the Sun. Solar power is sustainable and has low operational costs once the panels are deployed. Solar panels can power various systems, from onboard computers to propulsion thrusters. Significant limitations arise however as a craft travels further from the Sun. How Astronauts Breathe in Space Lithium Ion Batteries on Earth & in Space Space Satellites: Mechanics & Materials The power output of solar panels decreases significantly beyond Mars. This creates problems for missions to distant destinations like Pluto, over four billion kilometers away. In missions to the outer solar system, solar panel size would need to be greatly increased to generate enough power, adding weight and complexity. Solar power is susceptible to disruptions. Shadows of planets or other spacecraft can interrupt power generation, requiring implementation of battery systems for backup. Solar flares and other space weather phenomena can also damage or degrade solar panels. How Solar Panels Work Lithium (Li): Science, Health & Uses CubeSats: Science, Technology & Risky Business NASA image Nuclear Power: Radioisotope Thermoelectric Generators (RTGs) For missions beyond sunlight, or needing a reliable and independent power source, nuclear power is the alternative. The standard of deep space exploration is the Radioisotope Thermoelectric Generator (RTG). RTGs don't rely on nuclear fission as a traditional nuclear power plant does. They use the natural decay of radioactive materials, typically Plutonium-238. Plutonium-238 undergoes radioactive decay, releasing heat as a byproduct. This heat is then converted into electricity using thermoelectric generators (TEGs). Titanium (Ti): From Space to Earth & Back Transition Metals in Science and Health Platinum (Pt): Junk Metal to Pure Treasure TEGs use the Seebeck effect, in which a temperature difference between two dissimilar conductors creates a voltage, driving an electrical current. RTGs have many advantages. They provide a long-lasting, stable, and predictable power source, independent of sunlight or external conditions. They're ideal for missions to the darkness of space. Some deeper space uses include the Voyager probes, the New Horizons mission to Pluto, and the Curiosity and Perseverance Rovers on Mars. They can also operate in extreme environments. Building Robots: Elastomers, Metals & Plastics Copper (Cu) Effects on Human & Plant Health Silica, Silicon & Silicone: Differences & Similarities Mars Curiosity Rover (selfie) NASA's Voyager spacecraft have been exploring the outer solar system since the 1970s. The longevity and reliability of RTGs mean spacecraft can function for years without relying on sunlight. RTGs also have challenges. Plutonium-238 is a rare and expensive material needing specialized production facilities. Concern rise about safety and environmental effects of launching radioactive materials into space. The relatively low efficiency of TEGs means RTGs generate less electricity compared to comparable solar panels. However, they're essential for long-term missions. For instance, Curiosity Rover sends valuable data about Mars' environment and geology. Drone Warfare: Unmanned Combat Vehicles How Salamanders Regenerate Body Parts Self-Healing Silicone Technology in Robotics Mars has ice caps at both poles, together about the size of the Greenland Ice Sheet Comparison of Energy Sources The choice of energy source influences mission design, vehicle capabilities, and length of operational time in space. Solar Energy Pros : Abundant near the Sun: Solar energy is readily available for missions close to our star. Simple technology: Solar panels are relatively easy to manufacture and deploy. Low operational costs: Once deployed, solar panels have minimal maintenance needs. Cons : Ineffective at great distances from the Sun: Performance declines sharply as spacecraft move further away. Performance affected by solar conditions: Solar flares and dust can affect efficiency. Biometallurgy: Microbes Mining Metals Cell Communication in Living Organisms Difference Between Oxidation & Fermentation Nuclear Energy Pros : Consistent power output: RTGs provide reliable energy, crucial for long-term missions. Long operational life: Systems powered by nuclear energy can last for decades, providing a stable energy source.

Laser communication uses light to send data. It's faster and more efficient than radio waves. The amount of information transmitted is higher and it's currently used in space exploration and satellite operations. FSO: Wireless Transmission By Light Beam Earth Communication: Satellites, Spacecraft & Astronauts Satellite Radio Waves: Type & Function Lasercom is essentially the same as current free-space optical (FSO) communication. It uses lasers to transmit data through space. Infrared lasers give the best speed and bandwidth. Laser communication can transmit data at rates up to 100 times faster than traditional radio frequencies. Data is encoded by changing the properties of the laser light. In space, laser beams are usually invisible, unless they come into contact with matter, like particles or atmospheric conditions. In this case light scatters or reflects, making it visible. Magnetic Fields & Space Travel Genetic Engineering: Biotechnology of Change Nanorobots: Micro Robotic Tech, Ecology, Health How Laser Communication Works Encoding the Data:  As with radio waves, the data is encoded into a format suitable for transmission. Encoding happens through modulation, adjusting the light to represent desired information. Data is coded on light by modulating light intensity, frequency, phase or polarization to transmit binary data (1s and 0s) or more complex info through light pulses.  Generating the Laser Beam:  A laser source, typically a solid-state laser or a fiber laser, generates a highly focused and coherent beam of light. The laser must maintain signal strength and accuracy over vast distances. Water Pollution: Eight Countries in Crisis Silver (Ag): Ancient Trade to Modern Tech Nanorobots: Micro Robotic Tech, Ecology, Health Transmitting the Beam:  The laser beam is aimed and transmitted toward intended receiver. Pointing and tracking systems compensate for motion of transmitting and receiving platforms, and atmosphere disturbances. Receiving the Beam:  At the receiving end, a telescope or other optical receiver collects the laser light. The faintest of signals must be captured, as the beam spreads out a long way. Decoding the Data:  Collected light is then directed to a detector, which converts the light signal back into an electrical signal. This signal is then processed to extract the encoded data. Atmospheric Correction:  When communicating between ground stations and satellites, the laser beam passes through the Earth's atmosphere. This can cause distortions and signal loss due to atmospheric turbulence and scattering. Adaptive optics are used to correct this for better signal quality. Rare Earth Elements (REEs): Science & Environment Human Microchip Implants: Pros & Cons Effects of Extreme Heat on the Human Body Advantages Over Radio Waves The fundamental advantage of laser communication is its vastly increased bandwidth compared to radio waves. It's as if radio waves are a narrow road while laser beams are a multi-lane highway. Higher Bandwidth Laser beams use shorter wavelengths of light compared to radio waves. Shorter wavelengths allow for more data to be encoded and transmitted within the same timeframe, for greatly increased bandwidth. It enables download of high-resolution images, videos and data from space observatories and probes at rates previously unimaginable. While radio frequencies carry limited data, laser systems transmit much more. Faster Data Transfer Laser communication supports data rates up to 10 Gbps or more. Satellite operators can send complex data faster. Entire datasets can be downloaded in minutes instead of hours. This benefits time-sensitive needs like disaster monitoring and real-time analysis of space phenomena. Super Alloys in Space Exploration Solar Energy & Nuclear Power in Space Air Pollution: Science, Health & Economy Security Laser beams are directional, with signals concentrated in a narrow path. This makes them harder to intercept and jam. Security is a significant concern in communication, especially in space. The focused nature makes it difficult for potential eavesdroppers to capture the signals. Smaller Lighter Equipment For the same data rate, lasercom tech is smaller and lighter than radio wave systems. This is an advantage for space missions, where weight and size are integral to success. Smaller equipment leaves room for scientific instruments or increased mission capacity. Laser systems operate at higher frequencies, allowing them to send the same amount of data using less power. Laser systems resist interference better than radio frequencies. Although they're vulnerable to atmospheric disturbances, advances in technologies like adaptive optics overcome these problems. Laser communication can deliver high-quality data even when conditions aren't perfect. Recently, China achieves a major milestone, leaping ahead of US efforts. China successfully attains a 100 gigabit per second data transmission rate in satellite-to-ground laser communication.

Drone Warfare: Unmanned Combat Vehicles Building Robots: Elastomers, Metals & Plastics Titanium (Ti): From Space to Earth & Back Cubesat in orbit On December 7, 2021, NASA's Laser Communications Relay Demonstration (LCRD) is launched as part of USAF STP-3 to enable communication between geosynchronous orbit and the Earth's surface. In May 2022, TeraByte InfraRed Delivery (TBIRD) is launched on PTD-3 and tests 100 Gbit/s communications from a 300-mile orbit to California. Laser communications in deep space are evaluated during the Psyche mission to the main-belt asteroid 16 Psyche, launched in 2023. Deep Space Optical Communications (DSOC) increases communication efficiency. In April 2024, the test is successfully completed. The Psyche spacecraft transmits from a distance of 225 million km. Lasercom is currently in production by various ops like the Ecuadorian Space Agency; Thales Aliana Space (French/Italian); and Surrey Satellite Technology (UK). It's in development in several other countries.

Free-space optical (FSO) systems use light beams to transmit data. Known for high bandwidth, security and immunity to electromagnetic interference, they're a rising alternative to traditional radio frequency communication. Earth Communication: Satellites, Spacecraft & Astronauts Satellite Radio Waves: Type & Function Magnetic Fields & Space Travel About FSO Traditional wired and radio frequency (RF) systems have limitations as in bandwidth, security and susceptibility to interference. Free-Space Optical communication provides high bandwidth and immunity to electromagnetic (EM) interference. FSO systems, also known as optical wireless communication (OWC), use light beams, specifically lasers, to send data through the atmosphere. Lasers can carry information over long distances. Fossil Fuels: Ecology & Economy Carbon Dioxide (CO2): the Good & the Bad Silicon (Si) Metalloid: Prehistory into the Future Lasers carry electrical signals by transforming them into optical signals (light) for transmission, and then converting them back into electrical signals at the destination. This is the usual method for laser communication and fiber optic networks.  FSO is used in locations where installing fiber-optic cables is impractical or cost-prohibitive. This method reaches data rates comparable to and surpassing fiber-optic systems, ranging from 1 Gbps to 10 Gbps. Gbps, or gigabits per second, is a unit used to measure speed at which data is transferred across a network. It describes internet speed or network capacity, defining how many billion bits of data can be sent in one second. Genetic Engineering: Biotechnology of Change Nanorobots: Micro Robotic Tech, Ecology, Health Rare Earth Elements (REEs): Science & Environment Advantages of FSOs Ultra-High Bandwidth FSO systems achieve bandwidths surpassing fiber optic cables. This is due to the high frequency of light, which enables transmission of large files in a short time. FSOs are suited for video streaming, high-resolution imaging and large data transfers. Security RF signals can be intercepted and jammed. FSO beams are directional and require a precise line-of-sight connection. This makes it hard for unauthorized parties to tap into the communication link. Encryption methods can also be used in FSO systems. FSO can apply methods similar to those used in fiber-optic communications encryption, adding further layers of security. Effects of Extreme Heat on the Human Body Humans in Space: Effects on Body & Mind Cryptocurrency Scams: Goodbye, Money Electromagnetic Interference RF communication is plagued by interference from other devices on similar frequencies. FSO is virtually immune to EM interference. It uses the optical spectrum. This is especially valuable in hospitals, military operations and regions with heavy radio frequency interference, like urban centers. Rapid Deployment & Low Cost Compared to laying fiber optic cables, FSO systems are faster and less expensive. Installation is a matter of mounting transceiver units and aligning the optical beams. This eliminating need for trenching, permits and infrastructure costs. Rapid deployment capability makes FSO suited for temporary installations or situations where laying cables isn't practical. How Spacecraft Produce Water for Astronauts Oil Wars: A Global Power Play Microchips: the Real World Power fiber optics Uses Last-Mile Connectivity: FSO bridges the gap between high-speed fiber optic networks and end-users. Telecom operators use FSO technology to complement existing fiber-optic networks. With last-mile connectivity FSO reaches remote areas, and avoids the congestion of densely populated urban centers. Enterprise Connectivity: FSO enables seamless connectivity between buildings in a corporate campus or metropolitan areas to eliminate need for leased lines or complex RF networks. Cities increasingly adopt FSO systems for urban networking. Mobile Backhaul: FSO provides a high-bandwidth, low-latency solution for connecting cellular towers to the core network, supporting the growing demands of 4G and 5G mobile data services. Disaster Recovery: FSO can establish communication links in regions of disaster to connect with emergency responders and relief efforts. During natural disasters like hurricanes or earthquakes, these systems help coordinate rescue efforts, transmitting data at up to 1 Gbps. Space Debris: Coping with Dangerous Junk How Solar Panels Work Semiconductors: Materials, Methods & Markets Military and Defense: FSO is ideal for secure communication in military and defense. Data privacy and resistance to jamming are rather important. However, secure technologies are only as smart as people who use them, as evidenced by recent bumbles of the US War Department. Problems Atmospheric Attenuation: Rain, fog, snow, atmospheric turbulence and other factors like air pollution can scatter and absorb the light beam, to reduce signal strength and potentially interrupt communication. Line-of-Sight Obstruction: FSO requires a clear line of sight between the transmitter and receiver. Obstructions like buildings, trees or moving vehicles block the beam and disrupt the connection. Fixes Adaptive Optics (currently used): Techniques to compensate for atmospheric turbulence and maintain a stable beam path. Multi-Beam Systems: Using multiple beams to increase redundancy and improve link availability in bad weather. Advanced Modulation Techniques: Using modulation schemes less susceptible to signal degradation. Hybrid FSO/RF Systems: Combining FSO with RF communication for a resilient hybrid.

Human microchips are often smaller than a rice grain. In Sweden, implants are already in use for convenience. They unlock gym doors, enable payments and store vital info, but have potential drawbacks. FSO: Wireless Transmission By Light Beam Earth Communication: Satellites, Spacecraft & Astronauts How Solar Panels Work Thousands of Swedes have chosen to embed rice-grain-sized chips under their skin. The chip is usually implanted in the hand. It can act as a pass or e-ticket, for example on transportation. In some public transportation systems allow commuters to use implants for fare payments. The microchip can unlock the front door at home, and store emergency contact details, blood type and medical info. Microchips: the Real World Power Transition Metals in Science and Health Solar Panels & Batteries in Space Technology behind the implants is Near Field Communication (NFC), the same as for contactless payments. Chips communicate with NFC-enabled devices to trigger actions based on the stored data. Information is stored on human microchips, usually RFID or NFC chips, through a reader/writer device. This can send data to the chip, enabling it to store and access info such as unique IDs or other data.  Satellite Radio Waves: Type & Function CubeSats: Science, Technology & Risky Business Building Robots: Elastomers, Metals & Plastics Pros of Human Microchip Implants Convenience: Microchip implants simplify everyday tasks such as payments, and remove the need to carry cards or keys. Cutting-Edge Technology Perception: Being among the first to use such innovations increases social status with peers who value technology. Tech enthusiasts consider implants at the forefront of personal technology, aligning with a growing digital lifestyle. Improved Security: Implants can improve security. They provide secure access to buildings, computers, or sensitive data, and are less likely to be lost or stolen than traditional access methods. Up to 80% of users also have faith in the security promised by microchip implants. Unlike forms of identification such as keys and cards, microchips are nearly impossible to lose or steal. Self-Healing Silicone Technology in Robotics Biometallurgy: Microbes Mining Metals How Salamanders Regenerate Body Parts Criminals must resort to cutting off a person's hand to steal a wallet. However, the ability to encrypt data adds an extra layer of security, to protect sensitive information even if this should happen. Medical Applications: Beyond emergency contact information, microchips may be used to monitor vital signs, track medication adherence, or even deliver targeted drug therapies. . Streamlined Identification: Border control or airport security becomes faster and more efficient with implanted identification. Hands-free Control: Chips can integrate with smart home devices, for hands-free control of lighting, temperature, and appliances. Genetic Engineering: Biotechnology of Change Nanorobots: Micro Robotic Tech, Ecology, Health Platinum (Pt): Junk Metal to Pure Treasure Cons of Human Microchip Implants Privacy Risks: The biggest concern is potential for privacy violations. The chip can be hacked or tracked without user knowledge or consent. Risk of data breaches and unauthorized surveillance is a deterrent for the prudent. While implants can be more secure than traditional access methods, they are not foolproof. With every technology arise ways to hack it. Hackers can exploit vulnerabilities in the tech and gain access to sensitive information, or even remotely control implanted devices. Health Concerns: While generally considered safe, there are potential health risks associated with implantation, including infection, inflammation, and migration of the chip within the body. Long-term effects are unknown. Cryptocurrency: Finance in the Space Age Electric Vehicles (EVs): Creation & Operation Artificial Intelligence: Power of Prediction Social Stigma and Discrimination: The use of microchips can create a social divide, with those who choose to be implanted (or not) facing prejudice or discrimination. Conveniences for unimplanted people may seriously degrade, causing even the unwilling to get an implant. Concerns about mandatory implantation also raise ethical questions. "Mission Creep": The initial purpose of the chip expands over time, leading to the collection and storage of increasingly personal and sensitive data, or vast amounts of unnecessary data. Ethics: Mandatory chipping raises ethical concerns about bodily autonomy and the potential for government control. For example in 2025 the US is forcing greater control over citizens, with no end in sight. Throughout the world few governments can be trusted not to exploit this technology. Ad companies would like to tap into it too. While a grain of rice seems small, it's enormous compared to the microscopic world of nanorobotics. Nanobots have a multitude of uses and also arouse many fears.

Hamas and Fatah are the two main political parties of Palestine, with Hamas controlling the Gaza Strip and Fatah governing the West Bank. Conflicts between them exacerbate the trauma of ongoing war with Israel. Gaza Strip: Cause & Effects of War Iran: Perilous Power of the Middle East Houthi War in Yemen: Politics & Motivations Palestine once occupies all of Israel; the split occurs gradually The Gaza Strip is a densely populated territory bordering Israel, Egypt, and the Mediterranean Sea. It has been a focal point of the Israeli-Palestinian conflict for decades. The West Bank is a larger territory surrounded by Israel and Jordan further north. The two major Palestinian political factions, Hamas in Gaza and Fatah in West Bank, have a history of power clashes. Origins & Ideologies Fatah Founded in 1959 by Yasser Arafat, Fatah is a nationalist movement with a secular ideology. Initially it leads the Palestinian struggle for self-realization as the dominant force within the Palestine Liberation Organization (PLO). Advocating armed conflict at first, Fatah later reaches a compromise by negotiation with Israel. Top 5 Countries of the Global Space Race Russo-Ukrainian War: Motives, Propaganda & Technology Drone Warfare: Unmanned Combat Vehicles Palestine flag First Intifada The First Intifada (First Uprising) erupts in Dec 1987. It starts in the Jabalia refugee camp. An Israeli truck driver collides with parked civilian vehicles, killing four Palestinian workers, three of whom are from the refugee camp. Palestinians argue the collision is a deliberate response for the killing of an Israeli in Gaza days earlier, despite denials by Israel. It sparks protests, civil disobedience and violence opposing Israeli presence in Gaza. Graffiti, barricading, hurling stones and Molotov cocktails at the Israeli army and its infrastructure in the West Bank and Gaza Strip contrast with civil efforts. Civil protests include strikes and boycotts. Civilians refuse to work in Israeli settlements on Israeli products, refuse to pay taxes or drive Palestinian cars with Israeli licenses. This grassroots uprising ignites a renewed sense of Palestinian nationalism. From this platform emerges Hamas. Oil Wars: A Global Power Play Rare Earth Elements (REEs): Science & Environment China: Politics, Economy, Military & Modern Life Hamas soldiers Hamas The Hamas movement was founded by Palestinian Islamic scholar Ahmed Yassin in 1987 shortly after the outbreak of the First Intifada. The group is an offshoot of the Muslim Brotherhood. Hamas ideology is rooted in Islamic principles. It advocates establishment of an independent Islamic state in all historic Palestine, including present-day Israel. It rejects negotiation with Israel and maintains armed resistance. Hamas also opposes the PLO's approach. Its charter contrasts sharply with Fatah's vision of two states. Fatah openness to talks with Israel is seen by Hamas as betrayal. Rise of Tensions & 2006 Election Israel withdraws from Gaza in 2005. This action is put forward by Prime Minister Ariel Sharon. The purpose is to improve Israel's security and international status in the absence of peace negotiations with Palestinians. Following Israel's departure from Gaza, tensions between Hamas and Fatah escalate. In 2006, Hamas wins a surprise victory in the Palestinian legislative elections. This is largely due to widespread dissatisfaction with Fatah's governance. Accusations include corruption, and failure to make progress in peace negotiations. Extreme Heat: Effects on Infrastructure Artificial Intelligence (AI) in Human Warfare Fossil Fuels: Ecology & Economy Fatah flag 2007 Conflict and Split The election results trigger a power struggle culminating in violent clashes in 2007. Hamas forces seize control of the Gaza Strip, ousting Fatah and establishing its own government. Fatah, led by Mahmoud Abbas, keeps control of the West Bank. It continues to represent Palestine internationally through the Palestinian Authority (PA). The impact is profound. Gaza's unemployment rate soars to 40%, exacerbated by Israeli blockade and limited economy. Fatah's governance in the West Bank is challenged by public frustration over corruption and human rights violations. People demand reform. Over 70% of Palestinians in the West Bank support a unity government. Control and Governance Hamas in Gaza Hamas depends heavily on social services and military strength. Its Izz ad-Din al-Qassam Brigades maintain order and assert control. This approach complicates Hamas's relationships outside Gaza. Hamas governs through a network of institutions, providing social services, enforcing laws and maintaining security. Its rule has been marked by authoritarianism, restrictions on civil liberties and focus on power buildup against Israel. Classified as a terrorist organization by countries like the US and Israel, Hamas faces severe sanctions. This causes a further humanitarian crisis with 80% of the population reliant on aid. Iraq: Mesopotamia to Modern Middle East How the Cloud Works - Pros & Cons Robot Manufacture & Environmental Health Gaza ruins - houses Fatah in the West Bank Fatah's governing body, the Palestinian Authority (PA), has limited self-rule in parts of the West Bank. The PA, financially dependent on international aid, works to maintain security coordination with Israel. Conflicts & Alliances Fatah cultivates strong relationships with Western countries and moderate Arab nations, seeking support for a two-state solution. In contrast, Hamas allies with countries like Iran and Turkey in a broader Islamist context, opposing Western influence. Hamas-Israel Conflicts: Hamas has engaged in multiple armed conflicts with Israel, involving rocket attacks, cross-border incursions, and Israeli military operations in Gaza. Jerusalem, Israel Hamas-Egypt Relations: Relations between Hamas and Egypt fluctuate. While historical ties exist through the Muslim Brotherhood, Egypt mediates ceasefires between Hamas and Israel and controls the Rafah border crossing, a crucial lifeline for Gaza. Hamas-Iran Relations: Hamas receives financial and military support from Iran, which views it as a key ally in its regional strategy. This relationship has been a point of contention with Western powers and Arab states. Fatah-International Community: Fatah and the PA maintain strong relations with the international community, especially Western countries, who provide financial aid and political support. Robot Lubrication: Grease the Machine Artificial Intelligence (AI) in Human Warfare Myanmar (Burma): Beauty & Brutality US supports Fatah despite the group's failing ratings in polls The PA is involved in extracting natural gas from Gaza offshore reservoirs, together with the Israeli and Egyptian governments. PA and Israel get a cut of 27.5% each. 45% of the gas goes to Egypt for processing to be sold back to Palestine and other countries. Reconciliation Attempts Numerous attempts have been made to reconcile Hamas and Fatah and form a unified Palestinian government. Efforts have repeatedly failed due to deep-seated differences over power-sharing, security arrangements, and the future of negotiations with Israel. The Humanitarian Crisis in Gaza The ongoing division between Hamas and Fatah significantly contributes to the humanitarian crisis in Gaza. The Israeli blockade, imposed after Hamas' takeover, aided by Egypt and strictly reinforced in 2025, limits movement of goods and people. Gaza suffers shortage of essential supplies, clean water and health care; high unemployment, homes and infrastructures in ruins. The internal Palestinian political division further complicates aid delivery and reconstruction efforts. Effects of Extreme Heat on the Human Body Irrigation in History: Greening of the Land Potassium (K): Human Health & Environment As of March 24 2025, reported by Al Jazeera : "Israel’s relentless bombardment of Gaza continues, with at least 65 Palestinians killed in attacks across the Gaza Strip over the past 24-hour reporting period. Two Palestinian journalists have been killed in Israeli air strikes, including a reporter with Al Jazeera Mubasher whose car was blown up in northern Gaza." Due to the attacks, the United Nations withdraws a third of its aid workers from Gaza for their safety. The UN is a sorely needed humanitarian presence in the Gaza Strip. On March 25 people in Gaza gather to protest the Hamas presence, blaming the group for attacks on the Palestinians by Israel. The fact that the Israeli attacks are war crimes has no effect. The people are badly traumatized and just want the war to be over. The US blames Hamas for inciting the attacks and continues to back Israel despite civilian death toll. The attacks by Israel include shooting and bombings of refugees, who are following Israeli instructions to leave the region; airstrikes on refugee camps, hospitals and food lines.

Radio waves are part of the electromagnetic spectrum, created when electric charges move. Waves travel through space at the speed of light, and their frequency varies widely. Genetic Engineering: DNA Region Manipulation How Solar Panels Work CubeSats: Science, Technology & Risky Business radio satellites Radio waves have the lowest frequency and longest wavelength in the spectrum. Wavelengths range from a few millimeters to thousands of kilometers. The EM spectrum is a range of electromagnetic radiation wavelengths. In longest to shortest wavelengths, the spectrum consists of radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays. How Wind Turbines Create Electricity Magnetic Fields & Space Travel Humans in Space: Effects on Body & Mind Infrared Electromagnetic radiation, an electric and magnetic disturbance, races at the speed of light (2.998 × 108 m/s) though space. It has neither mass nor charge but travels in packets of radiant energy called photons, or quanta. The photons move in oscillating waves. The wavelength is the distance from wave crest to crest. Frequency is defined by the number of waves moving through a given point per second. Solar Panels & Batteries in Space Solar Energy & Nuclear Power in Space How Bacteria Survive a Nuclear Explosion cr: NASA Satellites use radio waves for communication, navigation, and Earth observation. A key advantage of radio waves is their ability to penetrate obstacles such as clouds, smoke, and some solid matter. Different frequency bands include very low frequency (VLF) and ultra-high frequency (UHF). Sources producing radio waves are natural events like lightning or human made signals from radio transmitters and TV broadcasts. Communication Satellites use radio waves for communication, navigation, and remote sensing. They transmit information over long distances. Geostationary communication satellites orbit the Earth at a height of about 35,785 km. They maintain a fixed position relative to the Earth. Thus the satellites can receive radio signals from ground stations, amplify them, and send them back. They enable Television broadcasting Internet connectivity Mobile phone systems How Spacecraft Produce Water for Astronauts De-Orbiting Satellites: Problems & Processes Space Debris: Coping with Dangerous Junk Global Positioning System (GPS) Radio waves are also key to the Global Positioning System. GPS satellites are in medium Earth orbit, about 12,000 km up. They continuously transmit signals including their precise location and the signal timing. A GPS receiver uses the signals to calculate its position by measuring how long it takes the signals to arrive. GPS can provide location accuracy within 5 to 10 meters for civilian devices. Earth Observation Satellites with remote sensing capabilities use radio waves to collect data about the planet. Synthetic aperture radar (SAR) satellites emit radio waves to bounce off Earth's surface and create detailed images. SAR is used to monitor significant events and changes like deforestation. It helps analyze damage from earthquakes or floods for relief efforts and recovery. In case of a hurricane, satellites provide data to help disaster preparation and response. Regions of Extreme Heat: The Future is Now Slime Mold: Brainless Wonder & Evolutionary Link What Robots Need to Function & Survive Satellites & Radio Waves: How They Work Uplink: Ground stations on Earth transmit radio waves towards the satellite. This 'uplink' carries instructions, commands, and data for the satellite to process. Transponder: The satellite is a type of relay station. It receives the uplink signal, amplifies it, then shifts it to a different frequency to avoid interference. Downlink: The satellite then transmits the amplified and frequency-shifted signal back down to Earth. The downlink carries the information gathered and processed by the satellite. Ground Reception: Ground stations, or smaller receivers like those in a GPS device or satellite dish, receive the downlink signal and decode the information. Air Pollution: Science, Health & Economy Robot Manufacture & Environmental Health Super Alloys in Space Exploration Frequency Allocation International organizations, like the International Telecommunication Union (ITU), allocate specific frequencies for different services, including satellite communication. This prevents signal interference. Frequencies C-band: Used for satellite television and radio broadcasts, with good resistance to rain fade. Ku-band: Also used for television broadcasts, offering higher bandwidth but more susceptible to rain fade. Ka-band: Provides even higher bandwidth for faster data transmission but needs more powerful transmitters and is vulnerable to atmospheric conditions. L-band: Used by GPS and other mobile satellite services. Problems While radio waves are essential for satellite communication, there are challenges to overcome. These include: Atmospheric Interference: Rain, snow and atmospheric gases can absorb and scatter radio waves, weakening the signal. Methane (CH4): Science of Microbial Gas Homeostasis: Internal Balance of the Body Ancient Grains: Wheat, Barley, Millet, Rice Blizzard Signal Interference: Other radio transmissions can interfere with satellite signals, causing data loss. Radio waves get interference from weather, other devices and crowded frequency bands. In dense urban areas, many devices can share frequencies, making it harder to get clear signals. Limited Bandwidth: Demand for satellite bandwidth constantly increases, partly driven by the popularity of IoT devices. This requires efficient use of the radio spectrum, for it is finite. Fixes Higher Frequencies: Moving to higher frequency bands offers greater bandwidth, but needs advanced technologies. Advanced Modulation and Coding Techniques: More efficient ways to encode and transmit data give greater capacity within a certain bandwidth. New Antenna Technologies: Advanced antenna designs improve signal strength and reduce interference.

The Houthi rebels, Ansar Allah ("Supporters of God") , are a Zaydi Shia movement from northern Yemen. A powerful force in the Yemeni civil war, they make headlines by blockading the Red Sea to protest Israeli attacks on Gaza . Iran: Perilous Power of the Middle East Gaza Strip: Cause & Effects of War Houthi War in Yemen: Politics & Motivations Origins & Mandate The Houthi movement goes back to the early 1990s. Founded by Hussein Badreddin al-Houthi, a prominent Zaidi cleric, It emerges as a cultural and religious revival among the Zaydi Shia community in Yemen's Saada province. The movement initially focuses on promoting Zaidi identity, marginalized by the government under President Ali Abdullah Saleh. The movement hopes to preserve Zaydi identity and address socio-economic grievances. By 2004 the Houthis change from a cultural group to an armed resistance. They accuse the Yemeni government of neglecting their needs and favoring Sunni factions. Oil Wars: A Global Power Play Water Pollution: Eight Countries in Crisis Russo-Ukrainian War: Motives, Propaganda & Technology Conflict The subsequent Saada Wars are six rounds of fierce fighting between the government and the Houthis. This increases Houthi political influence. Their grievances include government corruption and foreign influence. They accuse the Saleh government of being subservient to Western powers and Saudi Arabia. The Houthi advocate for a more just and equitable society based on Islamic principles. Their motto, "God is great, death to America, death to Israel, a curse upon the Jews, victory to Islam," encapsulates their anti-Western and anti-Israeli stance. They position themselves as defenders of Yemeni sovereignty. Weapons of Mass Destruction: United States Gaza, West Bank: Hamas & Fatah Iraq: Mesopotamia to Modern Middle East victims of Saudi-led airstrikes Popular Support Their rhetoric resonates with Yemenis who have faced such problems as such as an ongoing blockade and military aggressions. 80% of the population relies on humanitarian aid. Support is especially high in rural areas. Many residents perceive the Houthis as protectors against external threats like the Saudi-led coalition. They're opposed by Sunni residents. The coalition forms in March 2015. Saudi Arabia, leading nine countries from W. Asia and N. Africa, launches a military intervention at request of Yemeni president Abdrabbuh Mansur Hadi after he's ousted from Sana'a. Drone Warfare: Unmanned Combat Vehicles Nine Countries with Nuclear Weapons Space Debris: Coping with Dangerous Junk Houthis protest Saudi-led attacks on Sana'a, 2015 Organization The Houthis have a centralized and hierarchical structure. At the top sits the Supreme Political Council, the de facto governing body in Houthi-controlled areas. It's overseen by Abdul-Malik al-Houthi, who sets the strategic agenda. Below him, various military and civilian branches manage governance, military campaigns, and social services. Abdul-Malik al-Houthi Underneath is a network of committees responsible for governance in military affairs, finance and propaganda. The movement's strong leaders often comes from the al-Houthi family, who enjoy great influence and respect among followers. The operational structure is flexible. The Houthis adapt and decentralize operations when necessary, especially under intense military pressure. The Houthis have implemented local governance systems in the regions they control, providing services like education and healthcare. This approach has enabled them to fill the void left by state institutions. North Korea (DPRK): Total Control Regions of Extreme Heat: The Future is Now Nerve Agents (Nerve Gas) as Weapons literary rate for women in Yemen is only 40% (77% for men) Funding & Weapons Houthi funding sources are diverse and often opaque. They get strong support from Iran , who also finances Hamas in Gaza. Houthis otherwise generate revenue through taxation, control over economic resources like oil, and donations from sympathizers in Yemen and abroad. They get at least $700 million annually from external backers The Houthi arsenal is a mix of weapons. They're acquired in various ways, such as seized from the Yemeni military, procured through black market channels, and supplied by Iran. Weapons include assault rifles, rocket-propelled grenades, anti-tank missiles, and increasingly sophisticated drones and ballistic missiles. The latter are a direct threat to Saudi Arabia and other regional targets. The relationship between Saudi and Iran is complex. While both members of OPEC, they back separate factions, turning the Yemeni crisis into a proxy war. Saudi supports US and Israel, all labeling Houthis as terrorists. About Crude Oil & Natural Gas Cryptocurrency Scams: Goodbye, Money Myanmar (Burma): Beauty & Brutality US thwarting terrorists Popularity in Yemen The Houthis have strong support in the Zaidi Shia-dominated areas of northern Yemen. Their appeal comes from a combination of factors, including: Shared religious identity: A strong connection to the Zaidi Shia faith and a perceived threat to its cultural and religious traditions. Grievances against the government: Frustration with corruption, economic inequality, and marginalization. Effective governance in controlled areas: Providing basic services and maintaining order in areas under their control, often in contrast to the ineffectiveness of the central government. Their provision of social services like education and healthcare reinforces their legitimacy among local populations. Anti-Western and anti-Saudi sentiment: Resonating with those who resent foreign interference in Yemeni affairs. Yemenis in Sunni-dominated areas tend to view Houthis as authoritarian forces seeking to impose their own agenda through violence and intimidation. The Sunni oppose Houthi affiliations with Iran. Biological Warfare: Microbes & Insects Scheele's Green: History's Most Toxic Pigment Ugarit Royal Palace: Romancing the Ruins Sunni worshippers Typical Members The Houthis draw their members from a diverse range of backgrounds, primarily from the Zaidi Shia community. Age: A mix of young recruits, adolescents and experienced fighters. Gender: Fighters are mainly male; women take supportive roles in logistics, education and medical care. Economic Background: Generally from lower and middle-class backgrounds, often drawn from rural areas where poverty and unemployment are prevalent. Many combatants have reported joining due to a lack of local job prospects. This socio-economic backdrop motivates many to see the Houthis as advocates for their cause, trying to improve living conditions. OPEC: Organization of Petroleum Exporting Countries Robot Manufacture & Environmental Health Effects of Extreme Heat on the Human Body The Red Sea Crisis The Red Sea crisis starts Oct 19, 2023, when the Houthi fired missiles and armed drones at Israel. They demand a halt to the Gaza Strip invasion. It doesn't happen. The Houthis capture and aerially attack numerous merchant and naval ships in the Red Sea, bringing massive air strikes against them. The crisis is linked to the Gaza war, the Iran-Israel proxy conflict, the Iran-US proxy conflict and the Yemeni crisis. 2025 Situation & US Airstrikes In March 2025 Israel launches airstrikes on the Gaza Strip, killing many civilians, including children and two reporters, one from Al Jazeera news. Strikes decimate a Red Cross center, hospital and refugee camps. These acts are considered war crimes. Tensions erupt in Israel with the threatened removal of government opposition member Ronen Bar, and the continued airstrikes on civilians. Thousands of angry Israeli protesters take to the streets to condemn the government. The Houthis attack US warships in the Red Sea and send drone blasts to military sites in Israel. They assert their actions are a direct response to US support for worsening Israeli attacks on Gaza. Rohingya Genocide in Myanmar Uruk Mesopotamia: Forefront of Civilization Artificial Intelligence (AI) in Human Warfare Iran-made Shahed suicide drone In return, by March 26 2025 at least 17 airstrikes rip through civilian populations in Saada and Amran, Houthi territories in North Yemen. The strikes come from the US, backing strategic partners Saudi and Israel. They inflame tensions already heightened by prolonged conflict. US involvement creates a major escalation. Israel ramps up its actions, attacking hospitals, a Red Cross center, refugee camps and emergency food lines in Gaza. US president Biden in 2024 is ineffective against the Houthis. In 2025 the new president is much more aggressive and self-aggrandizing. Attacks are used as a show of US war power to intimidate or impress other countries. Consequences of the US Airstrikes Wider Regional Conflict: The targeting of US warships and alleged attacks on Israel raise the potential for broader regional conflict. Humanitarian Crisis: Airstrikes in Yemen further worsen the already dire humanitarian situation. The country has been ravaged by years of civil war. Increased Anti-American Sentiment: The alleged US airstrikes fuel anti-American sentiment in the region and supporters, potentially cycling into further attacks on US interests and personnel. Disruption to International Trade: Continued instability in the Red Sea disrupts international trade, including oil tankers coming from the rigs.

The modern Israel-Palestine conflict has torn up Middle East for over a century. Israel and Palestine both claim rights going back to Biblical times. Today Israel is on an genocidal mission in the Gaza Strip . Gaza, West Bank: Hamas & Fatah Gaza Strip: Cause & Effects of War Houthi War in Yemen: Politics & Motivations Nationalism & Colonialism The modern Israel-Palestine conflict goes back to late 19th century during times of rising nationalism in Europe. Jewish nationalism or Zionism is an effort to establish a Jewish homeland due to rising anti-Semitism in Europe. Simultaneously, the Palestinian Arabs who live in the region for generations start to form their own national identity. Palestine is then part of the Ottoman Empire. In the Balfour Declaration of 1917 the British government supports "the establishment in Palestine of a national home for the Jewish people." It's a catalyzing force. Iran: Perilous Power of the Middle East Yemeni Civil War: Internal & International Conflict Myanmar (Burma): Beauty & Brutality Flag of Palestine While promising a homeland to the Jews, it fails to address the existing rights of Palestinian Arabs, the vast majority of the population. As Jewish immigrants start to settle in the area, tensions escalate to violence. Between 1920 and 1921, riots in Jaffa and Hebron cause dozens of deaths and injuries on both sides. After World War I, the League of Nations grants Britain a mandate over Palestine. Jewish immigration increases significantly, especially in the 1930s. This heightens tensions with the Arab population. Arab riots and uprisings demand independence and an end to Jewish immigration. They're met with British suppression and growing Jewish self-defense organizations. Drone Warfare: Unmanned Combat Vehicles Fossil Fuels: Ecology & Economy China: Politics, Economy, Military & Modern Life Israeli flag Violence escalates. Palestinians see their land taken away. Zionists believe they're reclaiming their ancestral homeland after centuries of diaspora. The British Mandate cannot maintain order and relinquishes control in 1947. In 1947, the United Nations proposes a partition plan. This hopes to divide Palestine into separate Jewish and Arab states. Jewish leaders accept the proposal, but Palestinian leaders reject it. This plunges the region into the 1948 Arab-Israeli War. The war results in establishment of Israel and displacement of over 700,000 Palestinians, an event Palestinians still commemorate as the Nakba or "catastrophe." Following the war, Israel controls 78% of Mandatory Palestine. The remaining territories, the West Bank (including East Jerusalem) and the Gaza Strip, come under Jordanian and Egyptian control respectively. Rohingya Genocide in Myanmar North Korea (DPRK): Total Control Russo-Ukrainian War: Motives, Propaganda & Technology In the 1967 Six-Day War Israel triumphs over Egypt, Jordan, and Syria to take control of significant territories like the West Bank and Gaza Strip. This fortifies ongoing Israeli occupation. After the conflict, 400,000 Israeli settlers move into the occupied territories. Inflamed tensions disrupt peace efforts. The occupation is a source of constant friction. Israeli settlements and military control, coupled with restrictions on Palestinian movement and economic development, leads to the First Intifada (1987-1993). The First Intifada arises as a grassroots uprising by Palestinians against Israeli rule. The movement is marked by protests, civil disobedience and civilian clashes. It sees the emergence of Palestinian rights group Hamas . Wildfires & Climate Change: Lethal Cycle Water Pollution: Eight Countries in Crisis Extreme Heat: Effects on Infrastructure Hamas is currently backed by Iran, China and North Korea The Intifada brings international attention to the Palestinian plight. During this period 1,200 Palestinians and 225 Israelis are killed. The 1993 Oslo Accords represent a step towards peace. Both sides recognize each other's right to self-determination. They agree on the establishment of the Palestinian Authority (PA). The PA governs parts of the West Bank and Gaza. Unresolved issues of borders, refugees and the status of Jerusalem continue to cause grievances. Jerusalem’s status is still one of the most contentious issues. Both Israelis and Palestinians claim the city as their capital. Access to holy sites often creates violent confrontations. Global opinions on property rights vary. Air Pollution: Science, Health & Economy Weapons of Mass Destruction: United States Drone Warfare: Unmanned Combat Vehicles Jerusalem Frustration and escalating tensions over Jerusalem erupts into the Second Intifada of 2000-2005. Violence is fierce with over 4500 Palestinians and 1000 Israelis killed in the clashes. Since 2007, blockades of the Gaza Strip by Israel and Egypt create a massive humanitarian crisis. Restrictions on movement and limited access get worse. Israeli settlements in the West Bank are a main cause of discord. While the international community sees these as illegal, Israel argues they're essential for security. In 2022, around 700,000 people live in over 250 settlements. Settlements in West Bank In 2023 Hamas takes 251 hostages from Israel, triggering a full-scale Gaza war and blockades by Israel and Egypt. Most hostages are returned. 62 remain. Over half are thought to be killed in the war. China, unlike the West, doesn't consider Hamas a terrorist organization. China supports the creation of a "sovereign and independent Palestinian state" based on the 1967 borders, with East Jerusalem as its capital. In Yemen, the Houthis cause the Red Sea Crisis in 2023. They blockade the Red Sea in support of Gaza Palestinians, demanding an end to the war and Israeli blockades. The Houthis are also labeled terrorists by Saudi and US.

Israel targets Geneva Convention taboos like reporters and emergency shelters. The group Hamas, labeled as a terrorist organization by US and its allies, is given as the reason for the attacks. In late March 2025, desperate people in Gaza cry for Hamas to leave so the war will end. Israel is not punished for its acts, which are war crimes under the Geneva Convention. The attacks continue. Even if Hamas leaves, without help the Palestinians are on a path to final eradication.

The Red Sea crisis begins in October 19, 2023. The Houthi movement in Yemen ignites the conflict by launching missiles and armed drones at Israel in direct response to Israel's genocidal actions in Gaza. Houthi War in Yemen: Politics & Motivations Israel-Palestine Editorial: History to Modern Warfare Gaza, West Bank: Hamas & Fatah The Houthis, a Zaidi Shia Muslim group, launch a barrage of aerial assaults on merchant and naval vessels in the Red Sea. Despite being warned by Houthi leaders of retaliation, US gets involved. The Red Sea is an important passage for global trade. The blockade is motivated by the attacks in Gaza, the Iran–Israel proxy war, the broader Iran–United States tensions, and the prolonged Yemeni crisis itself. The Houthis, a Zaidi Shia Muslim group, invoke the crisis with missile and armed drone attacks aimed at Israel. This brazen move is a direct response to the Israeli offensive in the Gaza Strip. Houthis demand immediate cessation of hostilities. It doesn't happen. The Houthis' involvement quickly escalates. The group launches a barrage of aerial assaults against merchant and naval vessels on the Red Sea. Nine Countries with Nuclear Weapons Gaza Strip: Cause & Effects of War Houthi Rebels: Origins & Warfare They also capture a few, one of which they return. They have taken POWs, 153 of whom they release to the Red Cross in January 2025. Their campaign disrupts global shipping routes, forcing companies to reroute vessels around the Cape of Good Hope. This adds weeks to voyages and significantly increases transportation costs. It's not as bad as the blockades in Gaza preventing food, medicine and human aid reaching the two million Palestinians crammed into a 40 km long space, and Israeli strikes targeting refugee camps and food lines. The Red Sea blockade is felt globally, especially in the oil industry. The route handles 10% of the world’s oil supply. The Red Sea itself has 180 rigs, with constant ingoing and outgoing vessels. The Houthis efficiently put the most pressure where it hurts. Iran: Perilous Power of the Middle East Yemeni Civil War: Internal & International Conflict Water Pollution: Eight Countries in Crisis owww ... my money! While Iran gives them support, the Houthi leaders are scholars and strong strategists themselves. Founded by the cleric Hussein al-Houthi, the movement is now headed by his brother, Abdul-Malek al-Houthi. The Houthis are a not disorganized mob of rebels. In areas they occupy, they establish schools and health care, garnering support from the people. Houthis launch up to 30 strikes against Israeli targets in October 2023 alone. These are perceived not just as retaliation but as an assertion of their position in the region. The brazen approach draws international attention to the humanitarian crisis in Yemen. The humanitarian crisis is caused by funding cutoff, the civil war and other attacks. Effects of Extreme Heat on the Human Body Iraq: Mesopotamia to Modern Middle East Wildfires & Climate Change: Lethal Cycle By the end of October 2023, US airstrikes target over 40 missile launch sites as well as Houthi infrastructure in North Yemen. This attempts to send a message to Iran about its undesirable behavior. South Yemen is a stronghold of organizations like al-Qaeda and ISIS, both acting against the Houthis. ISIS sends suicide bombers to two Houthi mosques in Sana'a, killing many civilians and wounding hundreds. ISIS no longer has a solid presence in Yemen but is still considered an insurgency group. About 19.5 million people in Yemen, half the population, remain in need of humanitarian aid. Unlike Israel, who bombs aid workers in Gaza, the Houthis do not stop help from reaching beleaguered citizens. Much of the humanitarian crisis comes from the US unilaterally cutting off USAID. Humans in Space: Effects on Body & Mind Biological Warfare: Microbes & Insects Weapons of Mass Destruction: United States USAID sent billions of dollars to help citizens in crisis. Its cutoff in January 2025 causes massive suffering in many countries including Yemen. Back in the Red Sea, Houthi attacks on ships include US and UK vessels as well as Israeli. The United States, allied with Israel and the Saudi coalition, launches hundreds of air strikes. They allegedly target Houthi missile sites, drone launch facilities and other military infrastructure within Yemen. These strikes attempt to degrade the Houthis' ability to make attacks, and to deter further aggression. On March 27 two civilians are killed and others injured in US attacks on a stonemasonry. Seven civilians are injured in March 28 airstrikes by US targeting Yemeni shops and homes. The Houthis continue to demonstrate their efficiency at striking vessels in the Red Sea. About 30 have been damaged, and two (cargo) ships, one Greek and one from the UK, sunk. As a Houthi backer, Iran supplies military and aid, intelligence and strategic guidance. Iran's motives run deep. By instigating confrontations Iran diverts attention from domestic issues and assets dominance, much as US does. Drone Warfare: Unmanned Combat Vehicles Artificial Intelligence (AI) in Human Warfare Plutonium (Pu): Nuclear Weapons & Space The recent missile attacks in the Red Sea are part of Iran's ongoing proxy war with Saudi Arabia, Israel and other factions. Successful strategies like the Red Sea blockade bolster Iran's power position. According to polls, more than 70% of Americans support military aid to Israel during conflicts. While 2023 and 2024 attacks are carried out under US president Joe Biden, 2025 sees Trump in the seat of power. He cuts a deal with Israel's leader Benjamin Netanyahu and hits Yemen hard with firepower. This is both a challenge to Houthis and a show-off of US war strength to other countries. Netanyahu is not popular in Israel. Like the US president, who makes changes to elections laws, he removes his opponents from power so he can have it. On a flight to the US his plane has to be rerouted. He fears arrest in Europe due to Israel's spate of war crimes in Gaza. Nerve Agents (Nerve Gas) as Weapons Biological Warfare: Microbes & Insects Vibrio Cholerae : the Cholera Bacteria Gaza Gaza War: Conflict in Gaza is the primary catalyst for Houthi actions. Public outrage over attacks on civilians in Gaza help bolster support. In 2025 Israeli citizens surge into the streets to protest the Gaza war crimes and dictatorial grip of Netanyahu. Iran-Israel Proxy Conflict: The Houthis' actions are seen as an extension of the ongoing proxy war between Iran and Israel. Iran provides the Houthis with financial, military, and intelligence support, including advanced weaponry and training. The US and the Saudi-led coalition back Israel. Iran-United States Proxy Conflict: Support for Israel and intervention in the Red Sea draw the US into the broader Iran-United States proxy conflict. The US views Iranian support for the Houthis a direct challenge to regional stability and its own interests. Iran-Saudi Arabia Proxy Conflict: Iran and Saudi are also in a proxy conflict over influence in the Middle East and other parts of the Muslim world. The Saudi-led coalition in Yemen includes Kuwait, Egypt, Jordan and more. Iran and Saudi each provide varying degrees of support to opposing sides in warfare. These include the civil wars in Syria and Yemen, and other conflicts. The Yemeni Crisis: The Red Sea crisis arises from the ongoing civil war in Yemen, ongoing for nearly a decade.

Wildfires rage through forest, savannah and even urban regions. Frequency and intensity of wildfires increase dramatically as they're fed by climate change, and their heat and emissions in turn worsen its effects. Water Pollution: Eight Countries in Crisis Effects of Extreme Heat on the Human Body Air Pollution: Science, Health & Economy Wildfires happen almost anywhere. They can be caused by factors like careless campfires and lightning strikes. Climate change is increasingly identified as a primary factor behind the current wildfire crisis. Wildfires are a natural part of many ecosystems, but those today are different. They're more frequent, more intense, and cover larger areas, leaving scorched earth and devastation. Rising global temperatures, extended droughts, and shifting precipitation patterns elevate the risk of wildfires. When environments become dryer, the vegetation that usually retains moisture turns into fuel, making it easier for wildfires to start. Bioremediation: Organic Cleanup of Toxins Compost: Teeming Metropolis of Life & Death Secret Life of Rust: Power of Bacteria For example, in California, the average annual temperature has risen since the 1970s, contributing to a higher risk of wildfires during heatwaves. The 2025 wildfires in Los Angeles are proof of the escalating crisis. A series of fires in Southern California, specifically in the Greater Los Angeles area, causes at least 29 deaths, thousands of destroyed structures, evacuations and widespread power outages in January 2025. Regions accustomed to manageable burns now battle unprecedented infernos. Wildfire intensity threatens communities, destroys habitats and release massive amounts of carbon dioxide into the atmosphere. CO2 further exacerbates the problem. The cycle is driven by the aggressive relationship between climate change and environmental conditions conducive to wildfire eruption and spread. Nitrogen Fixation & Evolution of Plant Life Vermicompost: Composting with Worms Algae: Evolution, Science & Environment Many regions throughout the world experience increased occurrences of severe droughts, heatwaves, and intense storms. Extreme heat causes suffering and death in countries from the US to Asia. Heat-related weather affects vegetation, causing a drop in moisture. Dryness makes it easier for fires to spread. In regions like the western United States, wildfires are frequent, with a 300% increase in area burned between 1980 and 2020. In 2025, a March 1 release from the National Interagency Fire Center reads: "Fifteen new large wildfires were reported yesterday in the Southern, Rocky Mountain, and Eastern areas. Fifty large uncontained fires are burning in 16 states, 23  are burning in Oklahoma. Nearly 2,100 wildland firefighters and support personnel are assigned to incidents across the nation. Since January 1, 11,912 wildfires have burned 396,631 acres across the United States. This is above the 10-year average of 7,157 wildfires and below the 10-year average acreage of 541,795." How Salamanders Regenerate Body Parts Earthworms: Soil Health & Ecosystem Balance Irrigation in History: Greening of the Land As global temperatures rise, so does the energy in the atmosphere. A warmer atmosphere holds more moisture, leading to more powerful thunderstorms and, consequently, more lightning. As lightning is a major natural cause of wildfire ignition, a surge in lightning strikes creates greater risk of wildfires. A study from U of California reports a 25% increase in lightning strikes in some areas due to climate change. The fuel for megafires comes from the drying effects of climate change. Severe heatwaves contribute to widespread and prolonged droughts. The 2023 wildfire crisis in Canada follows periods of intense dryness or drought. In Australia the climate warms by more than one degree Celsius over the past century. This small rise is enough to increase the frequency and intensity of heatwaves and droughts. Eight of Australia's ten hottest years on record have occurred since 2005. Major droughts of the late 20th century and early 21st century in southern Australia are considered without precedent in the past 400 years.

Until the 2019–2020 Australian bushfire season, forests in Australia are thought to reabsorb all the carbon released in bushfires across the country. The 2019–2020 bushfires emit 400 megatonnes of carbon dioxide into the atmosphere, more than all Australia's emissions for three months. 2019 is Australia's driest year since 1900 with rainfall 40% below average. Handling fires can be limited by funding and equipment. The Forest Survey of India (FSI) sends daily satellite forest fire data to all states. It reports seven major fires in Jharkhand on March 24 2025. Five are in West Singhbhum district, and one each in Khunti and Pakur. Forest frontline ground crew have only fire blowers, beaters and fire rakes to fight the blazes. How Wind Turbines Create Electricity Regions of Extreme Heat: The Future is Now How Solar Panels Work Today in South Korea, the largest wildfires in its history rip through the land during an especially dry period. At least 27 people have died, most of them elderly, in the race to escape the fast-moving flames. Beyond the immediate destruction of homes and infrastructure, prolonged exposure to smoke from fires is a public health threat. Respiratory issues are dangerous for everyone, especially those with pre-existing conditions. Smoke and fires also disrupt ecosystems, displace and kill wildlife, and destroy habitats. Long-term consequences, including soil erosion and water contamination can persist for decades. Wildfires contribute to the climate change that fuels them with a growing feedback loop. As forests burn, they release stored carbon back into the atmosphere, accelerating global warming to increase risk of more wildfires.
